This document describes the features and characteristics of SPP16N50C3, SPB16N50C3, SPI16N50C3, and SPA16N50C3 Cool MOS™ power transistors. These products adopt a new high-voltage technology and have ultra-low gate charge, periodic avalanche capability, extremely high dv/dt rating, ultra-low effective capacitance, and improved transconductance. The products are available in different packages and have different ordering codes. The document also provides the maximum ratings for each model, such as continuous drain current, pulsed drain current, avalanche energy, avalanche current, gate-source voltage, etc.
